New York, have inventied certain new an l nsetful Impromments inFolclable .Velccipecles, 0f which the follow1ng 1s a spec1fication.

This invention relates to toy or pleasure Yehi0les such as tricyles 01'velocipedes and l1as partieular reference o a device 01 1na chine 0fthis c'haincter that is calculatecl to folcl o1 collapse so as to occupyvery m'uch less space than when in normal running positiorn Arnong the'objects of theinvention there- :iore is t0 provicle a trieycle orveloeipecle having a frarne, the several parts 0f which are soarticulatecl together as to pennit the1'n 10 be movecl 'relatively so asto occupy practically the same plane. 1

Another object of the invention is 130 previcle such connections betweencertain 0f the wheels ancl the frame members upon Wl1lCl1 they a1'ejournaled as t0 enable the wheels to be tu1ned with Tespect to the frameso as 'to lie in approximatelythe san1e plane, ancl as a result of asingle c0ntinuous movement.

A still further object of the inventiozi is t0 provicle a foldingvelocipede having a frame incl1icling 'relativ'ely movzible parts, theremwheels 015 the vehlcle being journalecl on the frame and theconstruction being such that Whn certain of the parts of 1'he fran1ea1'e swu'ng intotha plane of other parts thereof said rear wheels Willbe turned automatiCally so as to octzup;y the same plane, a planecoinciclent Wltl'l' 01 closiely parallel to the then plane 0f thefran1e.

With the foregoirig ancl other objects in flew tl1e invention consistsin the arrarigernent ancl Combinati0n 0f parts hereinafter describedancl claimed, and. while the invention is notrestriet-ed.'11uthe exaetdefiails of co nstruction disclosecl 01 suggested herein, st1ll :E r thep1ir1sblbf illustrating a p1actical embmliment the1eof reference is hadto the accornpanying drawings, in which like reference charactersdesignate the Same arts in the several views, and in which Figure 1 is asicle elevation of a preferrecl form of the invention in runningposition.
